yeahp. When i got a flat on the side of a highway during rush hour, the thing popped off while I had the whole wheel off of the car, so of course my audi just fell to the ground.

After 45 minutes of standing there like an idiot unable to contact anybody who would actually be able to help me, a technician that actually worked at the Audi Dealer where I bought the car stopped and helped me out.

I still don't have a replacement, so if I get another flat im SOL to change the tire myself.
